numeri delle pagine più grandi [risolto]

Salve. Io ho creato questo file di stile per gli articoli:

`
\setlength{\textwidth}{12cm}
\setlength{\textheight}{\dimexpr 39\baselineskip+\topskip+\headsep+\headheight\relax} % numero delle righe
%\setlength{\textheight}{17cm}
\setlength{\headsep}{26pt}
\setlength{\parindent}{9mm}

\def\calclinespreadfor#1{
\begingroup\normalsize
\dimen0=#1\relax
\count0=\dimen0
\multiply\count0 1000
\dimen0=\baselineskip
\divide\count0 by \dimen0
\ifnum\count0<1000
\count2=\count0 \count0=0
\else
\count2=\count0 \advance\count2 by -1000
\count0=1
\fi
\xdef\myratio{\number\count0.%
\ifnum\count2<100 0\fi
\ifnum\count2<10 0\fi
\number\count2 }
\endgroup
\linespread{\myratio}\normalsize}

\calclinespreadfor{13.7pt}

\calclayout

\usepackage{fancyhdr} % fancy (mettere fancy sempre DOPO la gabbia)
\pagestyle{fancy}
%\renewcommand{\chaptermark}[1]%
% {\markboth{\MakeUppercase{\thechapter.\ #1}}{}}
%\renewcommand{\sectionmark}[1]%
% {\markright{\MakeUppercase{\thesection.\ #1}}{}}
\renewcommand{\headrulewidth}{0.2pt}
\renewcommand{\footrulewidth}{0pt}

\newcommand{\pig}{%
\fontfamily{pig}\fontsize{7}{9}\selectfont}

\fancyhf{}
\fancyhead[LE,RO]{\pig \thepage \vspace{3.5pt}}
\fancyhead[CO]{\pig \rightmark \vspace{3.5pt}}
\fancyhead[CE]{\pig \leftmark \vspace{3.5pt}}
%\fancyhead{}
%\fancyhead[CO]{\footnotesize\headtitle}
%\fancyhead[CE]{\footnotesize\shortauthors}
`

Mi piacerebbe sapere come fare ad ingrandire solo il numero nella testatina.

Grazie. Ciao,
